Title:
METHOD OF PRODUCING A SULFIDE SOLID ELECTROLYTE MATERIAL, SULFIDE SOLID ELECTROLYTE MATERIAL, AND LITHIUM BATTERY
Document Type and Number:
WIPO Patent Application WO/2011/073798
Kind Code:
A3
Abstract:
A method of producing a sulfide solid electrolyte material includes: forming an intermediate having crosslinking sulfur but no Li2S, by vitrifying, in a first vitrification process, a starting material composition obtained by mixing Li2S and a sulfide of a group 14 or group 15 element such that a proportion of Li2S with respect to the sum total of the Li2S and the sulfide of a group 14 or group 15 element is smaller than a proportion of Li2S required for the sulfide solid electrolyte material to obtain an ortho composition; and eliminating the crosslinking sulfur by vitrifying, in a second vitrification process, an intermediate-containing composition resulting from mixing a bond cleaving compound, which cleaves a bond of the crosslinking sulfur, with the intermediate.
